Research and development cart robot / AGV - 4-wheel independent steering drive type, ROS compatible cart robot.
*The product image shows the state with the full surround bumper option attached.* The 4WDS Rover Ver2.1 is a mobile cart robot equipped with independently driven wheels on all four corners, allowing for smooth movement in all directions by steering each wheel. It can be utilized for a wide range of applications, including as a base robot for research and development, as well as for transport carts. This time, we have updated from the already released 4WDS Rover Ver2.0 to Ver2.1, incorporating user feedback and further improving reliability. It maintains the advantages of existing products, such as ROS compatibility and a variety of options, while achieving an even better and more stable user experience. **Features** - Accurate omnidirectional movement and high load capacity with independently driven wheels - Control via wired/wireless connection - Control through ROS message communication - Programmable with Arduino IDE - Easy operation with a dedicated wireless controller **Changes from 4WDS Rover Ver2.0** - Addition of current control circuit - Improved noise performance of communication path *For more details, please refer to the PDF document or feel free to contact us.*

Detailed information
-

The 4WDS Rover Ver2.1 supports three types of wireless communication: Wi-Fi, BLE, and Bluetooth Classic, as well as wired USB serial communication. By using specified commands, it can be controlled from various devices such as PCs and tablets.
-

The 4WDS Rover Ver2.1 supports ROS message communication. By connecting to a device running ROS via Wi-Fi or USB cable, control using ROS becomes possible. By using ROS message communication, command values for speed and turning can be sent to the 4WDS Rover Ver2.1 with just a few lines of code, allowing for a wide range of applications as a ROS robot. An introductory document and the following sample programs are included, making it easy for beginners to create and operate a control system in a ROS environment. *You will need to prepare a device to run ROS separately. *The operating environment for the devices we recommend will be described later. 【List of ROS Sample Programs】 - Control from a gamepad - SLAM (gmapping) - Navigation - Control from a mouse (touchpad) - SLAM (cartographer) *Additional setup of libraries not included with this product may be required. *An LRF is necessary for performing SLAM and navigation. The LRF option is convenient to use.
-

The control board of the 4WDS Rover Ver2.1, called "VS-WRC051," is equipped with the Arduino-compatible microcontroller ESP-WROOM-32. Therefore, you can create control programs for the 4WDS Rover Ver2.1 using the Arduino IDE. The included library contains motor control functions and communication functions, allowing you to create control programs with minimal development burden. *Note: When programming the VS-WRC051 using the Arduino IDE, an environment with Arduino IDE version 1.8.6 or higher is required.*
-

By using the gamepad-style wireless controller "VS-C3" included with this product, you can wirelessly operate the 4WDS Rover Ver2.1 without connecting to a PC or other devices. You can use the analog stick to move and rotate in all directions, making it useful for manual operation and for performing operation checks.
